INN3478C - Off-Line Multiple Output QR Flyback Switcher

Download the INN3478C datasheet PDF. This datasheet also covers the INN3464C variant, as both devices belong to the same off-line multiple output qr flyback switcher family and are provided as variant models within a single manufacturer datasheet.

Description

The InnoSwitch™3-MX together with InnoMux dramatically improves system efficiency by eliminating the boost and buck converter stages.

It also simplifies the development and manufacturing of multiple output power supplies, particularly those in compact enclosures or with high efficiency requirements.

Features

  • Primary sensed output OVP.
  • Open SR FET gate detection.
  • Hysteretic thermal shutdown.
  • Input voltage monitor with accurate brown-in/brown-out and overvoltage protection Full Safety and Regulatory Compliance.
  • Reinforced insulation.
  • Isolation voltage >4000 VAC.
  • 100% production HIPOT compliance testing.
  • UL1577 and TUV (EN60950) safety approved.
  • Enables designs that have “A” performance criteria for EN61000-4 suite of tes.
